Fully-Automatic battery charger : automotive Battery Charger 10-Amp 12V and 24V Fully-Automatic Smart, It's smaller but delivers more power, battery maintainer, trickle charger, plus battery desulfator,with Temperature Compensation,Charge or repair all 12V and 24V Lithium,LiFePO4,Lead Acid (AGM/Gel/SLA..) deep-cycle batteries, including AGM, GEL, SLA, and Flooded in cars, trucks, SUVs, motorcycles, lawnmowers, boats, marine, etc.8 kinds of mold test charging protection, safe and reliable: The charging cable is made of high temperature resistant and oxidation resistant copper wire, which is not easy to break. With over charge/over voltage/over current/short circuit protection circuit, with over current protection, short circuit protection, reverse protection, overheat protection, over voltage protection, under voltage protection and other functions.Easy operation, intelligent memory: Car battery charging mode has memory function. After charging, the default is the status mode before the last power failure. There are no complicated steps, just plugging and charging. Note: Power connection is required, Input voltage :100-240V 50/60Hz, output voltage/current :max 12 V10A, 24 V5AHigh power, fast, safe and accurate charging: The battery charger uses a large backlit LCD screen to clearly display the charging state; The integrated thermal sensor detects ambient temperature and reasonably changes the charging method to eliminate overcharging in hot climates and undercharging in cold climates.Scientific battery repair model: can help restore old/idle batteries and extend battery life. If the car battery charger does not charge the battery, use repair mode. High frequency and low frequency pulse techniques have good repair and activation effects. Note: It does not activate spent batteries or repair damaged batteries.
